invention relates to tire covers for the protection of spare tirecasings carried on motor vehicles.

The main objects of this invention are to provide an improved form oftire cover; to provide a tirecover which will fit so snugly that waterand mud will be excluded; and to rovide an improved form of tire coverwhich will not shrink, rot or easily tear.

Anillustrative embodiment of the invention is shown in the accompanyingdrawings,

Fig. 1 is a plan view of the improved cover, and its relative normalsize as compared with the tire it is designed to protect,

which is shown in dotted lines. I Fig'. 2 is a section taken on the line2--2 of lfiig. 3' is a crosssectional view showing the cover in positionon a'tire.

Fig. 4 is a friagmentary detail view from the line 44of 1g. 1.

Heretofore, tire covers have for the most part been made of cloth orother fabric which tends to shrink after the cover has been exposed towater. After tire covers have thus become weta number of times, thefabric rotsand is often .torn when it is attempted to assemble the coveron the tire to be protected. The material is non-elastic and snug fitsare diflicult to obtain. Water tight fits are not possible with suchcovers.

The above objections have been overcome by providing a cover which is anelastic,

than the tire it is designed to unitary cover. The cover iscircumferentially smaller and cross sectionallysmaller,

rotcct.

The tire cover shown in the rawings comprises a tube 1, preferably ofelastic rubber, circular in form and split longitudinally about itsinternal periphery. The marginal edges of the tire cover are providedwith snaps 2 and coac'ting fasteners 3 spaced apart for pnovidin meansfor securing the tire cover around t e tire.

In assembling the cover on the tire 4 which is held on the rim 5, it isnecessary to stretch the cover both circumferentially and crosssectionally, and when secured around 1 the tire by means of the snapsand their coacting fasteners, a water-tight fit is secured and thedifiiculties of shrinkage, rotting and tearing are done away with.

. plane of the tire as s own in Fi By stretching the tire'covercircumfer entlally is meant stretching it in the plane of the cover andtire upon which it is applied as shown in dotted outline in Figure 1. Bstretching the cover in cross sections diameter is meant that when thecover is applied toa tire the inner ripheral edges of the cover to whichthe listening means are attached are in spaced relation, and in order tofasten theedges together it has to be stretchedin a lane transverse toth 3. While but one specific embodiment of this invention has beenherein shown and described, it will be understood that details of theconstruction shown may be altered or omitted without departin spirit ofthis invention as de following claims.

-I claim: n 1. A spare tire cover comprisin a circular tube ofintegrally formed materi the entire ed by the from the area of which issubstantially uniform.

elasticity said tube being open around its inner periphery forassemblingon the tire,

said tube being circumferentially smaller,

and smaller in cross sectional diameter than the tire to be .covered, sothat said tube will have substantiall uniformwater-excludi contact witht e tire when assembl thereon, and co-acting means on the inner ripheraledges adjacent said opening for etachably securing said edges together.
